To all whom it may concern:

Be it known that I, Fanomrox M. Fpnmm, a citizen of the United States,read; at Revemin the county of Suifolk an State of ssachusetts, haveinvented wrtain Improvements in Coating Apparatus, of which t efollowing description, n con nection wit the acco anymg drawings, aspecificat on, like re erence characters on 10 the drawings indicatinglike parts in the several figures.

This invention relates to apparatus forapplying to \various objects acoating substance, as. for covering w1th blackmg or 16 other stain theperip eral portions or sides of shoe-heels. It is more particularlyadaptthrough the applying and gage members and more closely associatedarts; and a Fig. 5, a detail, part y in section, of the strfipmg devicefor the feeding disk. e frame 10, ,with its receptacle 12 for theblacking or other substance which is to be a plied to the work, togetherwith some of t c minor devices, generally resembles those of the crestheel blacking machine, which is the subject of tent No. 1,025,523,Furber, May 7, 1912,- an need not herebedescribed. In the frame isiournaled horizontall a main driving shaft 14 extending from t e frontto the rear and joined by a worm and worm-wheel 16 to a transverseintermediate shaft 18. This latter shaft is between definite lines,determined by the rand-crease at one side and the junction be- 1 tweenthe base and lift at the other, withis the portion 26 is out of axialalinement with the portion 22, it beinfiinclined downwardly with res tto the orizontal from ed for o rat upon heel-bases to which geared at 20to a section 22 of an operating are at ed ru ber lifts. shaft, whichturns in a bearing transversely In the use of heel-blacking'machines forof-the ap ratus at the front of the frame. 20 the pur just indicated,there is pre- C0nn to the section 22 by a universal sented t e problemof spreading upon the couplin 24 is a second section 26, formingheel-wall a substantially uniform coating an ang e with its companionsection.

of the fibers, which are situated in close'proximity to the inner wallof the plate. The outer portion of the sleeve 44 is threaded at 52 toreceive an internally threaded collar 54, which, contactingwith thebrush-body, clamps it in place against the plate, The exterior of thecollar is also threaded to receive the internally threaded hub of adished disk 56, the concave side of which is toward the brush. The edgeof the disk is shown asl ing somewhat outside the circumference o theplate '46, both of these being within the outer extremities of thebrush-fibers which furnish the applyin surface. Movement of the diskalong t e sleeve, it being secured at the point to which it is adjustedby a set-screw the hub, allows of a different degreev of compression tobe obtained by the contact of the disk. This forces the outer portionsofthe fibers against the plate, without interference with the adjustmentby engagement of the disk with the fixed base-portions. The extremeoutward adjustment is shown in dotted lines in Fig.

I This permits the effective width of the applying surface to be variedto adapt it to operate over heel-bases of different heights, thereremaining in the fibers a capacity to bend laterally on account of theprojection of the ends beyond the peripheries of the plate and disk. Atthe side of the brush where the uncoated portion of the work is withoutthe protection of the ge-disk, this bending is made less than at t eguarded side, because of the greater radial extension of the disk 56.The flexing preferably rather soft, permits the coating substance to beapplied without spattermg, and tends to so.that ail-accumulanot beproduced. This 1s of especial in! portance at the' lower portion of thebase,

slightseparation to prevent an excessive a plicatlon of the coatingsubstance along this hne. The relation between the disk 58 and the brushmay be altered by movement of the bearinge28 upon the bracket 32, thismovement ing provided for by the shiftmg of the slot 34 along the screw30. The edge 60 of the disk is adapted to enter the rand-crease of ashoe S, the heel-base H of which is to be blacked, To this heel-base isshown attached, this occurring prior to the blacking operation, a rubberlift L.

.with the section 22,

The disk 58 acts as a guide or ga e for the work, causing it to be heldin tile correct relation to the brush for this to ap ly the coatingsubstance across the side of t 1e baseto the extreme upper portion, at.the same time protecting the upper. The gage-disk also tends to advancethe work ast the brush, assisting the operator in this movement.Adjustment of the bracket 32 laterally of the axis of the shaft-section26 by means of the screw-and-slot connection at 40, 42 alters therelation of the appl ing surface of the brush to the gage-edge o thedisk, so that when the latter IS in place in the rand-crease, said brushwill act to, the best advantage over the outer surface of the base,giving the desired flexing of the fibers, without putting too muchpressure upon these. This position of maximum efficiency may bemaintained by this adjustment as the brush wears in use.

The coating substance is supplied from the receptacle 12 to the brush bya rotatable device, including a sleeve 62 fixed upon the shaft 18 andhaving oppositely extending arms 64, 64. Attached to the extremities ofthese arms are series of closely placed fingers 66-, the two sets offingers being staggered with respect to each other, so that they, incombination, operate over a practically continuous line. As the fingersrevolve in the direction of the arrow in Fig. 2, they dip into thecoating substance in the receptacle, and, upon leaving this, pass throuh the ends of the fibers 50 outside the perip eries of the plate 46 anddisk 56. This supplies the necessary amount of the substance to theapplying surface of the brush. Because of the angle which theshaft-section 26 car ing the brush forms its rotation, the receiving thecoating substance from the fingers diverges from the disk 58.Consequently, while, at the opposite side the disk and brush are closelyassociated, at the feeding point they are quite widely separated, so thefingers may act upon the brush without interference with the disk. Thefeeding device has another function. The fingers are curved forwardly inthe direction of rotation, and have upon the fibers a combing actionwhich, when they tend to become matted under the pressure of the workagainst them and the gathering of the coating substance, causes theirrearrangement by straightening and separating them. Preferably, theperipheral speeds of the brush and fingers are different, so that theline at which the fingers act angularly about the brush is varied,causing them to operate over the entire applying surface. The sleeve 62has at its inner side a flange 68, to which is attached a feed-disk 70provided with a substantially radial rim-portion 72 movable rom which itreceives rtion of the brush-fibers the side of the base. To establishthe proper overrun, either uppn ed feeding relation between the disks70' and 58, the, shaft-section 22 is adjustable longitudinally, so thatthe a plying surface of the rim 60 may be can to approach or retreatfrom the surface of the disk 7 To rovide for this, the shaft has,outside its ring, collars 74, 74, which may be adjusted upon it to varythe longitudinal position of the shaft. This adjustment occurs withoutdisturbance of the gearing 20 through elongation of the gear-teeth at76, J

while play in the connections of the couplin 2J4; revents interferencewith the connecte n the feed the coating substance upo ing surfaceof thedisk 70, and therefore the amount supplied to the disk 58, is determinedby a stri per-plate 77, which contacts with the f ing portion 72 of the7 0. The plate is mounted u n a spindle 78 movable lonitudinally t intoan opening in the frame and held variably in ition by a set-screw 82.Transversely t ugh the spindle, with its extremities projecting throu hslots 84 in the sleeve, passes a in 86, an between this pin and a collar88 est upon the sleeve is a helical spring 90. This spring exerts itsforce to thrust the stripper-plate yieldably toward the feedingiisk. Theextent of this move: ment may changed b a collar 92 threaded upon theouter an of the spindle 78, this collar contactin with the sleeve 80.Adjustment of the co ar so alters the relation between thecontactsurface of the late 77 and the feeding surface of the di '70 thata film of thecoating substance-of the desired thickness ma be carriedupon the latter and transferre to the ap lying surface upon the rim 60.-Yieldabe' scrapers 94, 94 operate u n the outer side of the disk 58,115in t e atented machine-previously referred to, eeping clean the surfaceover the shoe-upper. In employing my improved; machine to coat, as withblacking, the heel-base .11 upon the shoe 8', without, having thisblacking the upper of the shoe n the attac rubber lift L,- a brush is paced upon the shaft-section 26, the

The operator then,- startingat the unction between the side of the heel and the breast, applies theturning the shoe in the opposite direction to that in which the diskrotates, so that the points of engagement of the rim and the ap lyingsurface of the brush are gradually s ifted along the heel until theopposite line between the side and breast this travel of the shoe, theblacking from the receptacle 12 by means of the fingers 66 and arestraightened by said fingers, while the gage-disk is supplied over'itsside con tacting with the is e of the heel by-the disk 70. ConsequentOn account of the separation between the brush and the rim '60, theapplication of the blacking to the side of the heel, along the line ofthe ledge, is prevented from' bein while at the bottom of the si e,adjacent to the rubber lift, the adjustment of the disk 56 causes thefibers to accurately foland to work the coating out uniformly. Duringthis operation, the upper is effectively shielded by the body of thedisk 58. -'The direct connection of the shaft-sections assures aconstant speed of rotation and gage-disk, and this actuation, in spiteof the an lar relation between the sections, is 'etfecte by simplegearing.
